For Daenerys: Long snow-white hair and tasteful Winter clothing will turn you into the beautiful Daenerys Targaryen in no time. Make sure to curl your long locks and bring a dragon as your trusty accessory.
For Jon Snow: One of the most iconic characters we've seen, being Jon Snow should for sure be on your radar this Halloween. Bundle up in your largest faux-fur coat, flaunt your curly hair or slick it back into a low pony, and if you can, grow a 'stache.
